SPECIFICATION forming part of Letters Patent No. 568,478, datedSeptember29, 1896.

Application filed April 18, 1895. Serial No. 546,267. (No model.)

To (tZZ whom it may concern.-

Be it known that I, OLIN S. FELLOWS, a citizen of the United States,residing-at Middletown, in the county of Orange and State of New York,have invented certain new and useful Improvements in Sealed Packages, ofwhich the following is a specification sufficient to enable othersskilled in the art to.

which the invention appertains to make and use the same.

In my concurrent application, Serial No. 527,608, filed November 1,1894, I describe and claim a special construction of can in which theflange of an end plate fitting inside the can-body constitutes thestripping portion. In said case the flange is soldered directly to thecan-body, and the resistance of the solder has to be overcome instripping off the flange to open the can.

My present invention is an improvementupon the structure disclosed insaid prior application, the object being to afford a concavestripping-section unattached to the canbody and free from solder thatwill yield more readily to the action of the strip-winding key; andhence the invention consists, essentially, in forming one end plate witha flange fitting either inside or outside the canbody by which the endplate is soldered thereto, and also with a concave stripping portionwithin the line of the can-body, but not directly secured thereto, sothat the soldered joint is undisturbed during the operation of windingthe stripping portion around the shank of a strip-winding key. I thussupplement the ad vantages of strip-winding from a concave surface byreducing the resistance to be overcome by the strip-winding key to theminimum.

My invention also includes the special form of stripping-tonguehereinafter described and claimed.

In the accompanying drawings, Figure 1 is a sectional elevation of oneend of my improved can; Fig. 2, a sectional detail, on an enlargedscale, of the structure shown in Fig. 1; Fig. 3, a section of a portionof the end plate, looking toward the stripping-tongue; Fig. 4, asect-ion on plane of line 4 4, Fig. 3; Fig. 5, a section upon plane ofline 5 5, Fig. 3; Fig. 6, a section upon plane of line 6 6, Fig. 3; Fig.7, a plan of a portion of the end of the can, showinga section of astrip-winding key applied to the stripping-tongue Fig. 8, a view showinga modified form of stripping-tongue.

concave stripping-section as related to the can-body, end plate, andsoldered flange.

The end plate 6 is formed with a flange f, which fits over the end 0 ofthe can-body O, or inside the same, as in Figs. 13 and 14, and issoldered thereto in the usual way. The end plate e is depressedcentrally, more or less, to form the concave stripping zone or section.9, which may be so situated as to fit snugly within the can-bod y, asshown in the first eight figures of the drawings, or may occupy aposition within and beyond the canbody, as shown in Figs. 9 to 13,inclusive; and said strip 8 may extend either parallel to the can-bodyor at an angle thereto, as indicated in the drawings.

By forming a space 19 between the inner edge of the can-body and theinner surface of the stripping-section s I render it impossiblefor thesolder to reach and bind the said strip 8, thereby rendering thestripping operationmore free and uniform.

The stripping-tongue t may be secured to the strip 3 in any suitable orconvenient manner, and I do not confine the use of my concave strip 8 tothe form of tongue 15 and the method of attachment shown, although thelatter discloses points of novelty which I desire to cover as a specialconstruction.

The novelty in the construction of the stripping-tongue 15 consists inmaking its tongue proper, t, wedge-shaped, in placing its shank t insidethe strip .9, with the tongue 6 projecting through one slit 71 therein,while its other extremity projects slightly through another slit n inthe strip 8, and in perforating the strip 3, adjoining the shank 29, topermit' the entrance of solder between the 0pposed surfaces.

By making the tongue 15 pointed and wed geshaped I facilitate itsengagement with the slot or eye in the strip-winding key, while theprojection of the other extremity of the shank through the strip 5renders the connection between the strip 8 and tongue tmore substantial,since it not only admits of soldering at the point 01 but, as will beseen by Figs. 9 to 14, inclusive, show modifications in the form of myindependent reference to Fig. 5, affords more or less of a shoulder atthat point, which will effectually resist all tendency of the tongue topull out away from the strip 3 under the strain exerted by thestrip-winding key at the beginning of the stripping operation.

Vherer comparatively thin sheet metal is used for the end cap, theangles between the strip 8 and the portions of the end plate on eitherside maybe relied upon to weaken the metal sufficiently to determine andcontrol the lines of severance; but where the nature of the metalrequires it I bind the strip 3 with circuitous incisions it, or othersuitable lines of reduced thickness, which the strip 3 will follow as itis wound off the end plate and around the shank of the strip-windingkey,

By my invention I obtain an independent concave stripping section freeof the canbody and stripping from the end plate itself. The can-body,after the opening operation, is also left of full capacity and with amargin of safety above the contents of the can, as in my concurrentapplication, Serial No. 527, 008, hereinbefore referred to.

In my concurrent application, Serial No. 546,885, filed April 23, 1895,I describe and claim a sheet-metal can in which the edge of the can-bodyis bent overto form an inwardlyprojecting flange to which the end plateis soldered, the end plate being formed with a concave stripping-zonebelow the said joint and with its central portion below thestripping-zone; and I do not seek to cover such special constructionherein.

hat I claim as my present invention, and desire to secure by LettersPatent, is-

A sheet-metal can formed with an end plate having a peripheral flange bywhich it is soldered to the can-body, said end plate being depressedcentrally within the body of the can, and being bent abruptly at anangle to said depressed center, and between it and the peripheral flangeby which it is secured to the can-body, to form a concave strippingportion defined and limited by parallel lines of reduced thickness, saidstripping portion being provided with a tongue for engagement with astrip-winding key for the purpose and substantially in the manner setforth.
